Figure 1 is a plan View of my improved wire-drawing machine. Fig. 2 is a front view showing the machine in elevation.

sponding parts in all the figures.

In my improved machine by the arrangement of the driving-clutch shown in Figs. 4 and 5 the operator is enabled to start'the o wire-drawing drum 1 without shock. The draw-out drum 2 runs continuously and is, driven through the gears 3, 4,5, and 6, which form a part of the draw-out drum. The gear 3 is of less diameter than the gear 4 and the 5 gear 5 of less diameter than the gear 6 on the; draw-out drum. They act to rotate the draw: out drum at a slower speed than the wiredrawing drum. The starting of the wire through the die is thereby facilitated. In op- 40 eration the hand-lever 7 acts through the link 8, the bell-crank 0, the rock-shaft 10, and the levers containing the clutch-shoes 29. By throwing the lever 7in one direction the clutch will grip the drum 12, which is keyed to the sleeve 13. Thewire-drawing drum 1 is also keyed to the upper end of the sleeve 13. In throwing the lever in the opposite direction this clutch is released and the brake-strap 14 is tightened on the outside of the drum 12, which stops the wire-drawing drum. Thus it will be seen that by throwing the startingclass of machinery.

Similar marks of reference indicate corre-' ends of the friction-band together, thus tight- ;ening the band on the draw-ontdrum; The wire is first gripped by the tongs 1S. 'ver 15 is then thrown around, tightening the So lever in one direction thewire-drawing-dru m isstarted, by throwing it to a central position the clutch for driving said drum is released, and by throwing the lever farther over in the opposite direction a brake is applied to prevent the wire-drawing drum from turning.

Greater advantages are obtained by the starting and stopping of the wire-drawing drums, as by this arrangement the operator flo is enabled to start the drum without shock and instantly stop it fromrcither side of the machine and put a brake on, which in case of accidents is a very valuable feature in this The arrangement for drawing out the'wire or starting it through the die inthis machine has the same advantages as the mechanism to start the wire-drawing drum,.which con- I jSlStSOf a friction-band wrapped around the drawing-drum 2 and is operated by the lever 15,which has a cam 16,arranged so as to throw the ,lever 17 outward when the lever 15 is thrown in the position indicated by the dotted outline in Fig. 1.

i Throwing the lever 17 out draws the two The leband on the drum, which carries the tongs around with it, thus drawing out the end of the wire. opposite side of the drum and strikesthestiid '19, the lever 15is automatically thrown back, so as to release the grip of theband on the Edt'ttW-Oflt drum, releasing the tension on the 'Wire and the grip of the tongs on the same.

When the lever 15 has reached the Thooperator then has sufficient wire through the die to fasten the end in the vise 20, which is tightened by the crank 21.

Then the operator starts the wire-drawing drum by the lever 7. While a coil of Wire isbeing drawn through by the wiredrawing drum 1 the operator starts another wire through another hole in the die by means of'the draw-out mechaninm j ustdescribed. The dieis placed in the die or soap box 22, which swings on the pivot 23 and is adjusted for alinement in re- 'lation to the wire-drawing drums by the ad- I00 justing-screw 24. For various lengths of wire to start with the stud 19 is placed at differcut positions around the drum in the frame of the machine,'as it is obvious that wherever the lever 15 strikes the stud 19 the friction-band will be released and the tongs will let go of the wire.

Describing the clutch and brake in detail, the levers are keyed to double screws 26, having a right-hand thread on one end and a left-hand thread on the opposite end. By raising the sliding collar 27, which is connected by the links 28 to the lever 25, the clutch-shoes 2!) are opened, thus gripping the clutch-drum 12. These clutches are provided with maple-wood linings, so as to give considerable friction between the shoe and the inner surface of the clutch-drum. Lowering the collar 27 releases the pressure of the shoes, allowing-the clutch-shoes and clutch-shoe carrier 30 to revolve with the vertical spindle 31, to which the clutelrshoe carrier 30 is keyed. As the rockshaft 10, through the levers 32, lifts the sliding collar 27 the bell-crank 9, attached to the lever 33 through the link 34, oscillates the screw 35 in the opposite direction from the screws 35 in the clutch. The double screw 21'), fastened to the lever 33, is oscillated in the opposite direction from the double screws 26 in the clutch. By the proper arrangement ol:' the threads on the oscillating screws oscillating the shaft 10 in one direction tightens the clutch and releases the brake. Oscillating the shaft 10 in the opposite direction releases the clutch and tightens the brake. back and forth on clutch-shoe carriers 30, being guided by pins projecting upward from said carriers. (Shown as square blocks in Fig. 4.) As the distance which these clutchshoes must travel in order to clutch or release the clutch-drum is very slight, it is only necessary that there should be a slight clearance'between said shoes and the guidepins. Clutch-shoe carriers 30 comprise a sleeve keyed to the spindle 31, as shown in Fig. 5, and a projecting annular flange at the upper end thereof, which flange carries the guide-pins before mentioned and are cut away at opposite points to allow the levers l'or actuating the screws 26 to pass therethrough, as shown in top plan in Fig. 4-. In the periphery of the sliding collar 27 is provided an annular groove, (shown in section in Fig. 3 and in dotted lines in Fig. 2,) in which are located the coupling-pieces 11, carried by pins at the ends of levers 32, which construction allows the collar 27 to rotate independently oF the levers 32 while it is carried with said levers in their oscillating movement in a vertical direction.

The weight of the wire-drawing drum 1 and the wire carried by said drum 'is supported in operation at the upper end upon the vertical spindle 3t by the hardened screw 36, which bears upon the hardened plug in the upper end of the spindle 31. By this mcansan adjustment for wear is provided. 'lhelower draw-out drum 2 is supported upon Clutch shoes 25) slide the projecting sleeve-bearing 37, .which is a part of the center frame. Reference to the drawings, Fig. 3, will show that the upper end of the sleeve 37 is above the point at which the wire is drawn on the drum 1, as the wire is drawn out at the lower part of the drum near the flange 38. By this means the load due to drawing wire is supported directly by the bearing 37 and there is no tendency to bend the spindle 31 or the sleeve 13, thus producing a very rigid. and steady mo tion to the wire-drawing drum when in operatiou.

Another important object in a machine constructed as shown is that each wire-drawing block or wire-drawing machine is a complete unit by itself. Generally these machines are put up in lots of four to twelve or more, all attached together and driven by the same horizontal line-shaft 39. Generally one starting or drawingout attachment is used to drawv the wire out for several drums or as many as are contained in theline and driven by the main line-shaft.

By the arrangement herein shown and described one block or machine is a complete unit by itself and can be used alone or set up as the other machines are in lines of six to twelve or more, as desired.

Having thus described my invention, I'
